Cue the latest innovation: dual-video porn, which pits two YouTube-style videos head to head, giving each your partial, divided attention.

We’re not kidding: Pornhorneo (NSFW) takes the “adult YouTube” concept pioneered by YouPorn and Pornotube, and puts two videos on the screen, rather than one. This has been done for loftier purposes already - like comparing political policies on HeadtoHead08 - but these days the adult industry isn’t as cutting edge as it used to be, and there are even reports that social networking is now a more popular use of the web. Pornhorneo lets you vote for your favorite, or course, and embed clips elsewhere. The content is user generated and submitted via an upload form, the unnamed founders told us in an email.
